[0029] In this way, when the vehicle charging device provided by the present application is used, the control module controls the driving module 300 to start, thereby controlling the second docking module 200 to move along the guide rail 1, so that it moves to a relative position of one of the multiple first docking modules 100 that need to be charged, and then the control module controls the driving module 300 to stop running; the control module controls the driving part to start, so that the moving part moves with the plug 7 in the direction close to the socket 8 of the first docking module 100, so that the plug 7 docks with the socket 8, and the control module controls the driving part to stop running after the docking is completed; in this way, the charging gun 10 connected to the socket 8 on the first docking module 100 has a charging function and can charge the vehicle. When charging is completed, the control module can control the driving part to reset the moving part, and then control the second docking module 200 to move to the relative position of the next first docking module 100 that needs to be charged.
[0030] like Figure 2 and Figure 3 As shown, the first docking module 100 includes: a charging pile 9, a socket 8 is provided on the first end face of the charging pile 9, a charging gun 10 is connected to the first side face of the charging pile 9, and a circuit for connecting the charging gun and the socket 8 is provided in the charging pile 9; a guide hole 6 is also provided on the first end face of the charging pile 9; the second docking module 200 includes: an electric slider 2, the electric slider 2 is slidably connected to the guide rail 1; a docking box 4, a plug 7 is provided on the second end face of the docking box 4, and the second end face of the docking box 4 is arranged opposite to the first end face of the charging pile 9; a guide column 5 is also provided on the second end face of the docking box; an electric lead screw 3, a fixed end of the electric lead screw 3 is fixedly connected to the electric slider 2, and an output end of the electric lead screw 3 is fixedly connected to the third end face of the docking box 4; the third end face of the docking box 4 is arranged opposite to the second end face of the docking box 4; wherein the docking box 4 serves as a moving part, and the electric lead screw 3 serves as a driving part.

The horn hole section 61 is located outside the straight hole section 62. The diameter of the small end of the horn hole section is equal to the diameter of the straight hole section 62. The diameter of the large end of the horn hole section is larger than the diameter of the guide column 5. The diameter of the straight hole section 62 matches the diameter of the guide column 5. In this way, the guide column 5 first extends into the horn hole section 61 and then extends into the straight hole section 62, which facilitates the docking of the guide column 5 and the guide hole 6.

[0039] In this way, the new energy charging station parking lot provided by the present application will not be affected by factors such as grid capacity expansion, and all parking spaces can be equipped with charging functions at a relatively low cost. The control module of the vehicle charging device can automatically control the movement of the second docking module 200 to each first docking module 100 for docking according to charging needs, thereby meeting the charging needs of more vehicles in the shortest time, and solving the problems of new energy vehicles in the prior art such as difficulty in finding charging spaces, queuing for charging, and inconvenience in charging.
[0040] The new energy charging station parking lot provided in this application can be reconstructed on the basis of an existing parking lot, or it can be used when building a new parking lot. Any parking space in the new energy charging station parking lot can be a charging space.
[0041] like Figure 1As shown, in another optional embodiment of the present application, the parking lot of the new energy charging station is a flat parking lot of the new energy charging station, and multiple rows of parking spaces are arranged in the horizontal direction.

At least one second docking module 200 is arranged on each guide rail 1; the number of second docking modules 200 corresponding to each row of parking spaces is less than the number of parking spaces in the row. In this way, a small number of second docking modules 200 can be arranged to enable multiple rows of parking spaces to realize the charging function, and the cost is relatively low.
[0042] In another optional embodiment of the present application, which is not shown in the figure, the parking lot of the new energy charging station is a three-dimensional parking lot of the new energy charging station, and multiple rows of parking spaces are arranged in the vertical direction; the moving part of the second docking module 200 is connected to the fixed part of the second docking module 200 through a position adjustment mechanism, so that the moving part can move in the vertical direction relative to the fixed part; the position adjustment mechanism includes a driving member and a sliding member, the moving part is slidably connected to the fixed part in the vertical direction through the sliding member, and the driving member is used to drive the moving part to move in the vertical direction.
